If your GP cannot see you for weeks, ask your surgery whether it can assess you for a fit note by telephone, video or an online request. You can also ask the healthcare professional already treating you.
For the first seven calendar days of sickness absence, you can self-certify. If you need a private online sickness certificate instead, check that your employer accepts it before paying.
Being unwell is difficult enough without trying to organise paperwork before an employer’s deadline. When your surgery offers an appointment several weeks away, it can leave you unsure how to explain the delay to work.
Understanding your options can help you organise the evidence while keeping your recovery the priority.
5 Key Takeaways
- You can self-certify for seven calendar days, including weekends and bank holidays.
- Ask your surgery about its fit note request process rather than waiting for a routine appointment.
- Doctors, registered nurses, pharmacists, physiotherapists and occupational therapists can issue fit notes following an appropriate assessment.
- A private sickness certificate is different from an NHS Med3 fit note; employer acceptance matters.
- Tell your employer promptly if you are having difficulty obtaining the requested evidence.
Do I Need a Doctor’s Note Before Paying for One?
If your sickness absence lasts seven calendar days or less, you can self-certify. This means confirming your illness and absence yourself, using your employer’s form, an email or another agreed method. You do not need a healthcare professional’s certificate for this period under the usual sick leave rules.
Count consecutive calendar days, including days you would not normally work. For example, an illness lasting from Thursday through Wednesday covers seven days, even if you only missed five working days.
If the absence continues beyond seven days, a fit note is normally required. Our guide to self-certification and how it works provides further practical context.
How Can I Request a Fit Note Without an In-Person GP Appointment?
Ask your surgery how it handles fit note requests. In the 2026 GP Patient Survey, 30.8% of respondents in England last tried to contact their practice online. Check whether your surgery accepts fit note requests through its website or the NHS App. Include your absence dates, any previous assessment and your employer’s deadline. The practice may arrange a telephone or video assessment where appropriate.
A routine appointment date does not necessarily tell you when a fit note request can be reviewed.
However, a healthcare professional still needs enough information to assess your fitness for work; submitting a request does not guarantee that a note will be issued.
Your usual GP is not the only professional who can provide one. Doctors, registered nurses, occupational therapists, pharmacists and physiotherapists can issue fit notes when appropriately assessing your health and work needs. Ask the professional treating you whether they can help. This does not mean every community pharmacy offers a walk-in fit note service.
A fit note assessment can take place in person, by telephone or video, or through consideration of another healthcare professional’s written report.
Is a Private Sickness Certificate the Same as an NHS Fit Note?
People use “sick note” to describe several documents, so check what your employer means. A private medical certificate can provide clinical evidence of illness, but it is not automatically the same document as an NHS Med3 Statement of Fitness for Work.
| Type of evidence | What it does |
| Self-certification | You confirm a sickness absence lasting seven calendar days or less. |
| NHS Med3 fit note | A healthcare professional records their assessment of fitness for work and any relevant advice. |
| Private sickness certificate | A private clinician provides medical evidence; its use in place of a fit note depends on employer agreement. |
The government’s guidance for employers explains that private providers may produce reports containing equivalent information for employers to consider.
Before ordering private evidence, ask HR whether it meets the requirements for your absence and sick pay arrangements. A doctor’s registration helps you check their credentials. Document verification helps establish authenticity. Neither replaces checking that you have chosen the right type of evidence.
How Does an Online Sickness Certificate Assessment Work?
An online service should involve a clinical review. The doctor considers your symptoms, the timing of your illness and how it affects your ability to work before deciding what can appropriately be certified.
The exact process varies by provider. You may be asked to complete a medical questionnaire, verify your identity and explain your symptoms through a consultation or uploaded video. The reviewing doctor may contact you with further questions.
If the evidence supports issuing a certificate, the doctor signs it, and the provider supplies the document. Some digital certificates include a verification code. If information is insufficient, further evidence or a different assessment route may be needed.
Our doctors follow a medical and ethical Code of Practice when assessing requests. You can also read about getting sickness evidence without an in-person appointment.
What Information Should I Prepare for the Doctor?
Give an accurate account of your illness and its effect on work. Describe what you are having difficulty doing, rather than supplying only a condition’s name. Examples might include concentration, prolonged standing or lifting.
Requirements vary. As a practical example, ZoomDoc’s work sickness assessment asks for the following information:
| Information | What to include |
| Identification | A photo of your passport, driving licence or workplace ID. |
| Illness dates | When symptoms started and whether they are ongoing or resolved. |
| Symptom video | A 30-second to one-minute explanation of your symptoms. |
| Workplace details | Your workplace’s name and relevant information about how illness affects your work. |
| Regular GP details | Details of your usual GP, if you have one. |
Do not delay medical care while arranging paperwork. If you need assessment or treatment, contact an appropriate healthcare service; a certificate request should not replace that care.
How Quickly Can I Get a Certificate, and What Does It Cost?
Timing depends on the assessment route, the information available and whether further review is needed. A same-day service describes an intended turnaround, rather than a promise that every application will be approved.
NHS England recorded that 76% of non-clinically urgent general practice appointments were dealt with within 14 days of booking in August 2026. If your employer needs evidence sooner, explain that deadline when requesting an assessment rather than assuming you must wait for your routine appointment.
For a private service, check both the advertised turnaround and when the assessment team reviews applications. Missing evidence or a need for clarification can extend the time taken. Also confirm the period the certificate can cover, especially if you expect a longer absence.
An NHS fit note is free when you have been ill for more than seven calendar days. If your employer asks for medical evidence during the first seven days, a clinician may charge.
Government guidance says the employer should cover that cost. Ask about reimbursement before arranging a paid assessment.
Check what is included in the price and read the refund terms before ordering.
What Should I Tell My Employer If the Note Is Delayed or Questioned?
Let your manager or HR team know that you have requested an assessment and explain when you expect an update. Keep a record of your request and follow your workplace’s absence reporting procedure.
If your employer questions a certificate, ask whether the concern relates to the document type, the dates covered, missing information or authenticity.
The GOV.UK employer guide to Statutory Sick Pay evidence states that an employer cannot withhold SSP simply because you are late sending a fit note. This does not remove other eligibility or sickness notification requirements. Contractual sick pay is also governed by your employment terms.
If a disagreement remains, ask HR to explain its decision and seek advice from Acas or your trade union. If SSP has been refused, HMRC has a dispute route. Paying for another certificate before understanding the objection may not resolve it.
Choosing the Right Sickness Evidence for Work
Keep a record of your absence dates, any assessment requests and the updates you give your employer. Having those details together can make it easier to respond if you are asked for clarification.
If an online assessment suits your circumstances, you can apply through ZoomDoc for a private work sickness certificate for £49.
Our GMC-registered doctors review your information and can certify up to seven days of absence at a time, where clinically appropriate. Certificates are usually issued within one hour, subject to sufficient evidence and the doctor’s approval. Apply for an online sick note for work now.
FAQs
Can a Certificate Cover an Illness That Has Already Resolved?
A doctor may be able to provide evidence about a resolved illness if there is sufficient information to support it. Explain when symptoms started and ended. Retrospective coverage is a clinical decision, not an automatic entitlement.
Can I Request Sickness Evidence for Anxiety or Depression?
Yes. A mental health condition can affect fitness for work. Describe its effect on your daily functioning and work, and seek appropriate care alongside any documentation request.
What If I Am Still Unwell When My Certificate Ends?
Contact the clinician responsible for your care and tell your employer. Ask whether further assessment or a new certificate is needed. An extension depends on clinical judgement and should not be assumed to happen automatically.
Can I Return to Work Before My Fit Note Expires?
You can return when you feel able and your employer agrees, including before the expiry date. You do not generally need another healthcare appointment solely to confirm that return. Discuss any changes that would help you work safely.
Who Should Issue My Fit Note After Hospital Treatment?
Where possible, the healthcare professional responsible for your discharge should issue it if needed. Ask before leaving hospital rather than assuming you must obtain it separately from your GP.
Will I Get a Refund If My Employer Rejects the Certificate?
An employer rejecting a certificate does not automatically entitle you to a refund. Check the provider’s terms and ask your employer why the document was rejected before paying for another assessment.
Can I Use a Private Sickness Certificate for a Benefits Claim?
Do not assume that private workplace evidence meets a benefits service’s requirements. If your claim asks for a fit note, confirm the required document with that service and the healthcare professional treating you.
